Code 34 problem
I am getting a code 34 for the map sensor voltage low. I have checked the wires at the sensor and at the computer. There isn't any problem with wires in either place. Is there any other wires that I need to check or find?

replace the MAP and see what happens.
#3
the map sensor tested good

Is your truck running erratically? Try cleaning the contacts between the wire and the sensor? Maybe a lil electrical grease? That would be my first attempt...
#5
Have you checked the wiring between the MAP sensor and the ECU?
#6
yes, i have and I am still getting a weak signal
#7
What is the voltage being sent to the MAP sensor from the ECU? It should be +5V if I remember correctly. If this varies at all during operation, you either have a wiring problem or an ECU problem.
